"Pinwheel. Pinwheel, spinning around"

Belle is like a little pinwheel in her crib. We lay her down in the center of the crib parallel to the wall, and between rolling from side to side and back to front, and sort of writhing around, she often ends up perpendicular and in one corner of the crib. It is a fun game: where will our little pinwheel baby end up when we go to her after her nap?
